To allya/710m it may concern Be 1t known that I, RUSSELL HUFF, a citispaces 35 and 35, the space 35 being within zen of the United States, and resident of Dethe bore of the cylinder and the space 35 troit, ayne county, State of Michigan, being 1n`aXial alinement with the cylinder have lnvented certain new and useful Imwall These water spaces are connected by provements in Hydrocarbon Motors, of the passages 34 and 36 and are so spaced as to provide an extension of the annular space in which the sleeve valves are located. An inner valve sleeve 2O and an outer valve sleeve 21 are mounted to slide on each other in the cylinder. These valve sleeves are pro vided with ears 22, and connecting rods 23 connect these ears Wit-h the eccentrics 25 mounted upon the eccentrics are shown diagrammatically in Fig. 1 and areplaced about eighty degrees apart. The sleeves are'provided with inlet ports 28 and exhaust ports 29, communicatwhich .the following is a specification.

This application is .a division of my application, Serial N o. 505,735, led July 2, 1909.

his invention relates to the manner of cooling the cylinders of internal combustion engines :and particularly to cooling engines of the sliding sleeve valve type.

A feature of this invention consists in the construction of the cylinder head, which is cored so as to provide a water space and is provided with raised portions forming inlet and discharge passages connecting with the water space in the head. The head is of dished formation and by providing these raised portions the total depth of this dished portion which receives the spark plug is reduced thereby rendering the plug more ac-v cessible.

In the drawings: Figure 1 is a vertical transverse section of a sleeve valve motor; Fi 2 is a top plan view of one-of the cylin ers of such a motor, and Fig. 3 is a section on the line 3 -of Fig. 2; Fig. 4 is a ongitudinal transverse section through part of a cylinder taken on the line 4 4 of Fig. 3', and Fig. 5 is a side elevation of the cylinder headl removed from the cylinder.

Referring to the drawings, 11 designates the upper section of the crank case provided with integral side arms l12 for supporting the engine structure from the side bars of a motor vehicle, 13 the intermediate section, and 14 the lower section of the crank case. The crank shaft 15 is journaled in bearings" tlvely. The operation of the valves thus described will be obvious from the arrangement shown in Fig.' 1. The cylinders are provided with water jacket spaces 32. Each one of the cylinders is provided with a shallow elbow 33, communicating with the passage 34 and with the cavity 35 in the head.

discharge duct 36 upon the opposite side of the cylinder communicates with the pipe 37 leading to the radiator.y The inlet duct or channel 34 and the outlet duct or channel 36 are formed by raised portions on the cylinder head, this construction being clearly shown. By means of this construction the depth of the recessed portion 38 is decreased, and the spark plug 39 is rendered accessible so that it may be engaged wrench. This construction has a decided advantage over those constructions in which the cylinder head is provided with an annular space communicating with the cavity 35.

What I claim is: v

1. In a hydrocarbon engine, a one-'piece cylinder head cored to provide a water jacket. and provided with narrow raised portions forming oppositely arranged inlet and discharge ducts communicating with the cavity.

2. In a hydrocarbon engine, in combination, a cylinder head cored and dished to provide an annular water jacket cavity. a spark plug secured into the center of the head, said head being provided with nar- .a manner well sections are bolted together in the art.

understood by those skilled in The cylinders 16 are bolted to the crank case. These cylinders in the construction shown are cast in pairs. Each cylinden is provided with a cylinder head 17, provided with a downwardly extended'portion 18 of Smaller -diameter than the internal diameter of the cylinder, thereby forming an annularspace or chamber 19. The downwardly projecting portion 18 is provided with the usual packing rings. Each cylinder head 1s proivided with two concentric annular water valve shaft 24.
